@Mr_NutterButter we have much green electricity, but it's uncommon here in germany to heat with it (because it was deemed too inefficient..). you'd have to fit millions of houses with new stuff instead of central heat powered by gas. nobody does that if gas is cheap enough. i think in other parts of europe like france using electricity for resistance heating is more common. the sane alternative are heat pumps, but you can't easily retrofit them.
fun fact: meanwhile the greens in germany want to kill heating with wood because of the soot.
